Improvement in side-bar wagons



UNITED STATES PATENT OFT-Ton.

JOSEPH OFARBELL, OF MORRISON, ILLINOIS.

IMPROVEMENT IN SIDE-BAR WAGONS.

Specification forming part of Letters Patent No. 212,152, dated February 11, 1879 5 application tiled July 27, 1878.

To @Il 'whom it mayconcerot:

Be it known that I, JOSEPH OFARRELL, of

Morrison, in the county of Vhiteside and,

State of Illinois, have invented a new and useful Improvement in Side-Bar Spring-Wagons, of which the following is a speciiication Figure l is a top view of the running-gear of a side-bar wagon to which my improvement has beencapplied. Fig. 2 is a vertical longitudinal section ot' the same, taken through the line w x, Fig. l. Fig. 3 is a detail sectional view, showing the connection between the springs and side bars.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish side-bar spring-wagons, which shall be so constructed that the elasticity of the springs may be regulated as required, which will prevent the springs from being broken by the rebound, and which will enable better results to be obtained with a less amount of steel than when the ordinary construct-ion is used.

A are the forward wheels ofthe wagon. B aie the rear wheels. Gis the forward axle. D is the rear axle. E is the head-block, and F are the side bars. The forward ends of the side bars, F, are connected with the head-block E, and their rear ends are connected with rear axle, D, by bolts, clips, or other suitable means. As thus far described there is nothing new in the construction.

G are the springs, which may be made ot' one or more leaves, as may be desired, and which are placed directly beneath the side bars, F. Upon the ends ofthe springs G are formed lugs g', which overlap the sides of the side bars, F, and have holes formed through them to receive the bolts H. The bolts H pass through slots f in the side bars, F, which are strengthened and protected frornwear by metal plates I, attached to them.

Slots f for the bolts H may be formed in the side bars, F, at one or both ends of the springs G, to give the necessary play to the said springs. In the latter case, rubber blocks J should be placed iu the ends of the slots f for the bolts I-I to strike against, as shown in Fig. 3. A

To the middle parts of the springs G are attached, by clips or other suitable means, the ends ot' two cross-bars, K, to which the wagonbody is to be attached.

By this construction the elasticity ot' the springs may be increased and diminished by moving the bars K closer to and farther from the centers of the springs G.

By this construction, should the wagon be overloaded, the bolts H will be drawn to the inner ends of the slots j", and the springs G and side bars, F, will become trusses, and capable of sustaining a great weight.

By this construction, also, the springs G being placed directly beneath the side bars, F, the said springs cannot be broken by a rebound.

Having thus described myinvention, I claim as new and desire to secure by Letters Iatent- In combination with the wooden side spars, F F, the springs G G,` arranged underneath. the side spars,'hinged at one end and sliding in boxes at the other end, said boxes being provided with rubber cushions on each side ot' the sliding part, and the springs being connected near the center by cross-bars K K, for

supporting the wagon-body, substantially as" herein set forth.

JOSEPH OFABRELL.
